Power semiconductors for demanding applications
Powerex specialises in the development and production of power semiconductors for industrial applications. The range includes power diodes, thyristors, IGBT and SiC solutions, and power modules.
Powerex components are designed for applications where reliability, high power, and long lifespan are essential. Think of energy, industrial installations, transport, railways, and other demanding applications.
Master Chips helps you select the right Powerex components for your application.
Expertise in power electronics
Powerex builds on decades of experience in power electronics. The company has been producing power diodes and thyristors since 1962 and combines this expertise today with modern technologies for energy conversion and power control.
An important asset is the ability to develop customer-specific solutions and smaller product series. This allows Powerex to respond to technical requirements for which a standard component is insufficient.
Power Diodes
Powerex offers various types of power diodes for rectifying and switching high currents and voltages.
The range includes:
- standard diodes
- fast recovery diodes
- welding diodes
- diode modules
The different versions enable application in a variety of industrial power systems.
Thyristors
For switching and controlling high power, Powerex offers an extensive range of thyristors and thyristor modules.
The range includes:
- phase control thyristors
- fast switching thyristors
- AC switch thyristors
- thyristor modules
- combined thyristor/diode solutions
IGBT & SiC
Additionally, Powerex offers IGBT, HVIGBT, and SiC solutions for applications where efficient switching at higher powers is required.
Silicon Carbide (SiC) technology is particularly suitable for applications that operate at higher temperatures and switching frequencies and can contribute to more compact and efficient power electronics.
Customer-specific solutions
Not every application can be solved with a standard component. Together with Powerex, we examine which specific diodes, thyristors, and modules need to be developed or customised.
Possible adaptations include:
- specific dimensions or enclosures
- customised connections and terminals
- specific markings
- additional electrical testing
- component selection for series or parallel connection
- solutions for specific mechanical or electrical requirements
This flexibility makes Powerex particularly suitable for projects with specific technical requirements or smaller production series.
Solutions for obsolete components
A power component that is no longer produced can pose a significant problem for industrial installations. Replacing an entire installation is not always necessary or desirable.
Powerex offers solutions for obsolete and end-of-life power components. Existing components can be analysed and, where possible, replaced with a standard or customised Powerex solution with similar mechanical and electrical properties.
This can significantly extend the lifespan of existing equipment.
Assembly and renovation
In addition to individual components, Powerex also realises complete assemblies around its power components.
Existing assemblies can also be refurbished, for example by replacing components and cleaning or reusing heat sinks. This can be an interesting solution when an installation is still technically perfectly usable, but certain parts need replacing.
Applications
Powerex components are used for:
- industrial drives and motor control
- railway and transport applications
- energy production and distribution
- renewable energy
- electric vehicles
- UPS systems
- induction heating
- welding installations
- medical equipment
- aviation
- industrial power electronics
Need help choosing?
Selecting a power component depends on various parameters, such as voltage, current, switching frequency, thermal load, and the specific application.
